MACHINE FOR MAKING CANDY.

Application filed December 8, 1919. Serial No. 343,253.

The invention lrelates to machines forV making candy. I

The `object of the invention 1s to provide improved means for feeding a strip of candy to mechanism for twisting or otherwise shaping the strip into pieces of commercial size. Another object of the invention v1s to provide improved feeding mechanism for a` 'strip of candy which is adjustable so that it may be used to feed strips of different shapes to the nishing mechanism;

The invention consists in the several novel features hereinafter set forth and more particularly defined by claimsat theconclusion hereof.

In the drawings: Figure 1 is a side elevation of a machine embodying the invention. Fig. 2 is a longitudinal section. Fig. 3 is a rear elevation. Fig. 4 is a section on line H of Fig. 2. Fig. l5 is a section online 5 5 of Fig. 2. Fig. 6 is an inside elevation of the adjusting bracket, the hubs of the rolls adjusted thereby being js hown in section. Fig. bracket for the rolls. machine.

` The continuous length or stream of candy passes from a suitable supply over a table 20 and through a nozzle 21 to a pair of continuously rotating coacting shaping and feed rolls 22 and 23. The lower roll 22 is slidably mounted upon, and rotatable with, a hollow shaft 24'and the upperroll 23 is similarly mounted upon a hollow shaft 25. These shafts are mounted in brackets 26 and`27 which are secured on a mainframe A. 'j These rolls are provided with peripheral grooves 2S and 29 which are adapted to shape the continuous strip of candy into thevde'sired cross-sectional form and` size .or diameter.

Fig. 8 is aplan of the In practice, some twisted vcandy is round' and the grooves 28 and 29are shaped to make the strip cylindrical or round.V The grooves 2911` on the vroll 23 coacting withlthe cylindrical surfaces 28' for the lower roller 22 are adapted to shape the strip or stream into triangular form of different sizes.

passes through a suitable stationary guide 30 and 'thence to a pair of combined gripping fand feed rolls .31 and 32. This guide 30 1s formed of upper and lower sections 43 and 44 between which passages are formed corresponding substantially to the different shapes given to the candy by the shaping rolls, these passages being alined with the respective grooves in saidrolls. This guide is secured by screws to the inner side of an adjusting bracket 36. Roll 31 is slidably mounted on and rotatable vwith a hollow Vshaft 33 and roll 32 is similarly mounted on la hollow shaft 34. Shafts 33 and 34 are mounted in suitable bearings inl the frame brackets 26 and 27. Rolls 31 and 32 are grooved similarly to the shaping rolls 22 and 23 so they will be adapted for handling allY of the shapes and sizes formed by the shaping rolls.

In machines for twisting' or otherwise shaping vthe strip, mechanism for act-ing upon the strip issuing from the rolls 31 and 32 is usually adapted to operate upon a strip at a given point, and to adapt the shaping and feed mechanism for cooperation with the finishing mechanism, the rolls 22 and 23, 31 and 32 and the guide 30 are conjointly and transversely adjustable to permit any of thevgrooves in these rolls to be brought into position to deliverV the candy to or in alinement with the axis of the twister or fin ishing mechanism. For this purpose, all of these rolls are slidable on their respective shafts so that they may be adjusted transversely and are connected. to their respective shafts so they will be rotated thereby in any adjustment. For the purpose of effecting conjoint, transverse adjustment of all of the rolls, a bracket 36 is fitted with terminals or forks 37 for the hubs of rolls 22, 23, 31 and 32 respectively. A screw 3S is provided with a crank 42 and is threaded to a sleeve 41 which is fixed in bracket 27 and has its inner end provided with a flange 39. The latter is rotatably held in a cap 40 on one side of the adjusting bracket 36. The lower section 44 of guide 30 is secured to bracket 36 by bolts 45 and the upper section 43 is secured to t-he lower section by screws. Rotation of the crank 42 will shift the screw 38 longitudinally and the latter, through bracket 36, will conjointly shift all of the rolls and guide 30. As a result of this construction, the shaping .rolls 22 and A23 and the con-` engaging grooves inV tinued feed and gripping rolls 3l and 32 and the intermediate stationary guide may be conjointly adjusted transverselyto bring strips of different shapes into correct'position to feed the stick to tlie'tivister or finishing mechanism.

To guide the operator in truly positioning the desired grooves of the shapingand feed rolls into desired aliiiement, a gage i6 is pivotally held on a cross rod e7. The latter is supported in brackets 26 and27. The gage is provided with a finger e8 having a pointed edge which is adapted to be swung downwardly into either of the groovesiii the upper rolls 23' to determine Whether the center of the grooves is in alinement with the axis of the finishing mechanism.' The gage is provided at one side of its pivot with a Weight 49 which is adapted to normallyh'old the gage inoperative and against a stop 50 on a collar 5l. on the rod if' lien the groove which is to be used is brought into aliiiementwith the pointed edge of the gage, the feed-mechanism will be correctly set to deliver a strip of the desired shape to the finishing mechanism.

' In practice, it is necessary to heat the shaping and finishing rolls to keep the candy hot, and for this purpose the shaft's2el and 25 for the rolls 22 and 23 and vthe shafts and 34 vfor the rolls 31 and 32 are hollow and steam is circulated through them. in

opening 50 is formed in each of thesesliafts and an elongated opening 5l" is formed in the hub of each of said rolls. Each opening 50 communicates with an opening 5l in allof the transverse adjustments ofthe rolls, so that steam Will be supplied to the rolls in all of their adiustments. Steam is supplied into the shaft 24 for the roll 22 by a pipe 53. fr pipe conduct-s steam from the other end of shaft 24 vinto onev end y of the shaft 25. An exhaust pipe 56 is connected to the other end of shaft 25. ljipe 57 suoplies steam to one end of thehollow shaft 83 of roll l'and1 a pipe 58 conducts steam from the other1 end of the shaft to one end ofthe shaft 3e for the roll 32. An exhaust pipe 59 is connected to the other end of shaft l 34.- 'lhese shafts and steam pipes are connected Vby suitable stufling bones 5e. f

Rolls 22 and 23 and 3l and 32 are conp tinuously driven to supplyl a strip to the finishing mechanism. VThe driving mechaV- nism lforthese rolls comprises a transverse shaft 60 which is provided with fixed and loosepulleys 61 and 62. A pinion 68 meshes with va gear 64; on a shaft 65Qvvhich ismountedili brackets 26 and 27 and isprovided( at In,termeshingl one end with a pinion 66. gears 67 and 68 on shafts 2e and 25 respectively are driven bylpinion 66 Whichmeshes With the gear 67. Intermeshing gears 69 and i 70 on shafts Se respectively are also driven pinion 66 which meshes with the'gear 'desired' shape and size.

lThis driving mechanism serves to operate the shaping and feedvrolls continuously. tivister-casing composed of sections 73, 75,

' The operationof vthe' machinerfvvill be as follows: "Shaping rolls 22 and `and the gripping rolls 3l and 32a-ndV guide 30 will be first adjusted`l into position by'screvv-rod 3S to bring grooves,ifor,giving ,the'continuous strip of candy the desired shape land size, into alinenient withv and into position to feed then shapedfstrip into the twister-or finishing mechanism. ssuming .the machine to be running, a continuous: stream or 'strip of candy Will be fed through the nozzle 21 to the rolls v22l and 23, thence through the guide 30 to the gripping andfeed rolls 3l and 32.9 While Vthe candy'j'is ,passing through the rolls. it'Will be kept hot so it can` be handled.V .Rolls 22 and 28 Will shape tlieregular round "strip into a strip of the The shape f the strip kwill be retained While it is pas/ sing through the stationary guide 30 and inthe feed .and grippingrolls 3l and 32.
